Hello i am quite scared right now so i apologize for the long story...
Yesterday at the office, an external firm fixed a decoration on the wall halfway the hallway. To fit this, he used a laser tool that was projecting a vertical line to the front on the wall but also to the left and right into nowhere meaning the beginning and ending of the hallway. He used a Hilti pm 4-m multiline laser tool that stood on the ground at foot height. The specs are <1mW 635nm Class 2 with a battery life of 8 hours.
Ok now before i continue you must know this: The hallway left side is a white wall and the right side are diffused windows and the sun was shining very bright for this time of the year. It was around noon when the sun was at it's highest.
So next i had to pass through the hallway and with the sun being that bright, i focused my eyes on the ground not knowing that the laser thing was standing there. Next i felt something that i can best describe as contraction of my eye muscle of some sort, like when you get from a dark room too a bright lit room your eyes do something "strange" ...or when you get hit by a laser, it's some kind of "blast" in your eye that you not hear nor feel but it is there. This happened for about 2-3 seconds.
At this point i just thought it was just the sun shining in my eyes so i moved on, and suddenly at the middle of the hallway, i saw the laser machine at my feet that was shining a line towards me on the ground, not in my eyes because i was to close at this point.
So i began to wonder. because in the past i had a supermarket laser shone in my eyes and it felt like the same "blast". Back then the blink reflex saved me but now i did nothing special because at no point when i was walking toward the laser, again not knowing it was there, i never saw a light that was bright enough to draw my attention like every laser should when in use?
So my first question is, can the sunlight de-brighten the start point (not the projection) of a laser so that it's not noticable but still in use? If so, will it still have the dangerous effects/strength?
Second, can a laser still damage your retina if shone in your peripheral vision?
Third, should i be concerned that this laser damaged my eyes given the "blast" time, if it was from the laser line?
Any thoughts on this? Because i really don't have a clue and don't know if i should be worried.. I added a drawing to illustrate this story.
At final i do mainly computer work, already slept pretty badly before this incident so pretty tired.
Because the only thing i am feeling is a sort "hit on the eye" pain and inflammation at the surface. I can't say i am seeing more blurry than usual and i can't say i see more floaters than usual. Also i don't see any afterimages i think.
Hopefully someone can help me! Thanks!
